Daily and Periodic Maintenance Guide

Daily Maintenance (Before & After Each Test)

1. Check the air inlet and outlet of the cooling system: remove dust, debris to prevent air duct blockage.

2. Inspect touch screen, meter and alarm indicators to confirm no fault warning.

3. Verify emergency stop button function is normal, no damage to the control panel.

4. Check copper busbar terminals: no loose connection, no overheating or discoloration.

5. Confirm fan running sound is normal, no abnormal vibration or noise.

Periodic Maintenance (Monthly / Quarterly / Annual)

1. Monthly: Tighten all high-voltage wiring terminals; clean surface dust of resistor elements.

2. Quarterly: Calibrate voltage, current and power measurement meter; test all protection interlock functions (overheat, overcurrent, fan fault).

3. Annual: Inspect resistor elements for aging, cracking or deformation; check insulation resistance of high voltage loop; inspect container sealing, anti-corrosion coating, lifting lugs.

Notice: All high-voltage maintenance work must cut off all power supply, follow high-voltage safety operation specifications, operated by certified electricians.

Frequently Asked Questions

Q1: What is the temperature rise limit of the resistive elements under continuous full-load operation?

A: The resistor elements are designed with a max temperature rise of 375K at rated power. With adequate forced-air ventilation, the unit can sustain full-power continuous running without exceeding the insulation temperature class.

Q2: Does this 2200KW 10.5KV AC Resistive Container Load Bank support stepwise adjustable loading and closed-loop automatic test mode?

A: Yes. It features multi-stage step loading with fine resolution. It can work with external test instruments for automatic load cycling, steady-state holding and generator protection relay testing.

Q3: What protection functions are integrated for medium-voltage safety operation?

A: It is equipped with over-temperature protection, over-current protection, fan failure interlock, emergency stop, high-voltage door interlock and earth fault monitoring. All protective signals can be uploaded via Modbus-TCP.

Q4: What is the altitude and ambient temperature operating range for rated capacity output?

A: Rated full power is available from -10°C to +40°C, up to 1000m altitude. For sites above 1000m or higher ambient temperature, power derating calculation will be provided.

Q5: Can the Resistive Container Load Bank record test data locally and export reports after the generator or UPS test?

A: Yes. It has built-in data logging function to record loading status, voltage, current, power and temperature. Test logs can be exported for FAT, SAT and site acceptance documentation.

Q6: What is the withstand voltage level of the 10.5kV high voltage compartment?

A: The HV compartment complies with standard power frequency withstand voltage test at 42kV / 1min, suitable for generator and transformer acceptance testing.

Q7: Is it possible to add reactive load (inductive/capacitive) besides the resistive load?

A: Yes. We can integrate RLC combined load on request, to simulate power factor variation for grid-tie inverter and genset power quality tests.

Q8: How do you handle harmonic distortion during loading tests?

A: This is a pure resistive Resistive Container Load Bank, which introduces negligible harmonic distortion. It is ideal for harmonic-sensitive power system acceptance tests.
